Pearson 5V0-22.23 New Attempt

The purpose of the TRIM/UNMAP process is to reclaim disk space that is no longer used by the guest operating system or the virtual machine. TRIM and UNMAP are commands that allow the guest operating system to inform the underlying storage layer that certain blocks are no longer in use and can be freed up. This process helps to improve storage efficiency and utilization,especially for thin-provisioned disks that grow dynamically as data is written to them. The other options are not correct. The TRIM/UNMAP process does not collect vSAN log files, repair internal cache errors, or delete orphaned snapshots. These are different tasks that are performed by other tools or processes.

The VMware solution that requires vSAN usage is VMware Cloud Foundation. VMware Cloud Foundation is an integrated software stack that bundles compute virtualization (VMware vSphere), storage virtualization (VMware vSAN), network virtualization (VMware NSX), and cloud management and monitoring (VMware vRealize Suite) into a single platform that can be deployed on premises or as a service within a public cloud. VMware Cloud Foundation relies on vSAN as the primary storage solution for its workload domains, which are logical pools of resources that can be used to run different types of workloads. The other options are not correct. VMware Horizon, VMware Telco Cloud Automation, and VMware Aria Automation are VMware solutions that do not require vSAN usage, although they can benefit from it. VMware Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, and it can use any supported storage solution, including vSAN. VMware Telco Cloud Automation is a cloud-native orchestration and automation platform that enables communication service providers to accelerate the deployment and lifecycle management of network functions and services across any network and cloud. It can use any supported storage solution, including vSAN. VMware Aria Automation is not a valid VMware solution name.

To view the resynchronizing metrics, the vSAN administrator should open the Backend performance category. This category shows the performance of vSAN data components, such as read/write latency, IOPS, throughput, congestion, and resync traffic. The other categories are not relevant for this task. Disks shows the performance of physical disks in the cluster, Host Network shows the network performance of vSAN hosts, and Resvnc Latency shows the latency of resynchronization operations.

To configure vSAN Direct, the administrator must meet two requirements: a valid vSAN license for the vSAN cluster and unclaimed disks in the hosts for vSAN Direct. A vSAN license is required to enable vSAN features and services, including vSAN Direct. Unclaimed disks are local storage devices that are not used by vSAN or any other service, and can be claimed by vSAN Direct to create datastores for persistent storage. The other options are not requirements for vSAN Direct. HA is an optional feature that can be enabled on any cluster, but is not specific to vSAN Direct. A dedicated network for vSAN Direct is not necessary, as vSAN Direct uses the same network as vSAN. An integration with vSAN File Services is not required, as vSAN Direct does not provide file shares, but block storage. References: Set Up vSAN Direct for vSphere with Tanzu; vSAN Licensing Guide
